Suddenly, small bumps are appearing only under my chin. Am I the only one experiencing this?

Lately, strangely enough, my whole face looks fine, but small, bumpy spots are popping up under my chin and along my jawline.

It's not a big, red pimple, but it feels like something is raised when I touch it, so it's kind of stressful....

I haven't changed any cosmetics recently, and I've been washing my face as usual, so I don't know why only this side is like this....

It feels a bit similar to when I wear a mask for a long time, and I also wonder if it's because I haven't been able to sleep....

I'm trying to hold back because I keep touching it and worry it might make it worse, but I'm also confused whether this is an exfoliation issue or a lack of moisture. If anyone else experiences breakouts specifically on their chin, I'm curious how you manage it.

I also want to know if it will subside on its own, or if there is something I need to do in the beginning. If anyone knows, please share!!
